Background: Implant esthetics may benefit from individualized zirconia abutments copying the emergence profile of the natural tooth and delivered within days after immediate implant insertion.
Purpose: To investigate the esthetic outcome of the Copy-Abutment technique using the Pink Esthetic Score (PES).
Materials And Methods: A total of 77 patients with single-tooth implants in the anterior maxilla restored at the day of immediate implant placement using Copy-Abutments and provisional crowns were followed-up after 1 week, 1 month, 4 months, 6 months, 1, 2, 3, 4, and 5 years to assess implant esthetics.
Results: PES ranged between 7 and 14 (median: 13) and improved significantly between the 6 month and 1 year follow-up (p < .001), then remained stable up to the fifth year. Significant improvement was seen for the variables PES-6 soft tissue color (p = .002) and PES-7 soft tissue texture (p < .001) up to the 1 year follow-up, while PES-5 alveolar process deficiency deteriorated (p = .016). Mean mucosal recession was 0.26 ± 0.86 mm (range: 0-1.6) after 5 years and not related to gingival biotype.
Conclusion: Copy-Abutments for immediate restoration of implants in the esthetic zone show satisfactory long-term esthetic outcomes.

Objective: To evaluate the amount of residual cement after cementation of implant crown abutments with rubber dam and retraction cord with copy abutments techniques.
Material And Methods: Thirty single posterior metal-ceramic implant-supported restorations were delivered to 20 patients. The crowns were fabricated with occlusal openings obturated with composite, and then luted with resin-reinforced glass-ionomer cement on customised standard abutments.

Residual cement around implant crowns can cause peri-implant disease, which can be minimized by precementing on a copy abutment. This article describes the use of polytetrafluoroethylene (PTFE) tape to allow an intraorally delivered custom or stock abutment to act similar to a copy abutment. It requires minimal change to the restorative dentist's routine and helps minimize the risk of cement-induced peri-implant disease.

Different techniques have been proposed for cementing crown restorations to implant abutments without excess cement extruding beyond difficult-to-access restoration margins. In one approach, a copy abutment is fabricated onto which the cement-filled crown is fitted extraorally, allowing excess cement to be easily removed before intraoral transfer. This article presents a modification of this technique, wherein hot melt thermoplastic material is used for the copy abutment instead of polyvinyl siloxane.
